Colin Kaepernick has been placed on injured reserve by the San Francisco 49ers, ending his season and possibly his career with the franchise.

Kaepernick, who was on the injury report Friday, told the 49ers that he wanted to undergo surgery on his left, non-throwing shoulder, prompting the team to put him on IR.

There have been reports of Kaepernick dealing with a torn labrum in his left shoulder.

Kaepernick on Friday told the Sacramento Bee he initially suffered the injury in a Week 4 loss to the Green Bay Packers.

Kaepernick was not listed on an injury report until after the Niners' Oct. 22 loss to the Seattle Seahawks, in which he was sacked six times.

It was in that offseason when Kaepernick signed a $126 million contract extension that was lauded at the time as being very team friendly. While he is due to make $14.3 million in 2016, $16.9 million in 2017, $17.4 million in 2018 and $19.2 million in 2019, per ESPN Stats & Information, the guarantees do not vest until April 1 of each calendar year.
